27 Claims. (Cl. 12 i) This invention relates to machines for effecting relative movement of shoes and lasts and is herein illustrated as embodied in a relasting machine of the type disclosed in an application for United 5 States Letters Patent, Serial No. 595,810, filed February 29, 1932, in the names of Harold S. Pym and- John M. Whelton. In that machine provision was made for holding a last stationary while various instrumentalities engaged the shoe to urge the shoe upon the last. Among the shoe engaging instrumentalities was included a friction member which acted against the shoe bottom.

An object of the present invention is to provide an improved machine of the character under consideration. In accordance with a feature of the invention, the illustrated machine is provided with a pair of members engageable with the shoe bottom, with supporting means constructed and arranged to enable each of the shoe engaging members to be urged independently of the other upwardly against the shoe bottom, and with means for operating the member-supporting means to cause the members to seat the shoe upon the last. In the illustrated machine one of the shoe engaging members consists of a friction pad engaging with the bottom of the forepart of the shoe and the other of a roll engageable with the bottom of the rear of the shoe. The provision for independent operation of thesemembers facilitates the operation of the machine upon shoes the arch of the shanks of which varies over a wide range. Thus, in dealing with a shoe having a very steeply arched shank, the roll may be forced upwardly as may be necessary to maintain pressure against the receding shank portion of the shoe. In the illustrated machine the friction pad and the roll are moved rearwardly in unison, in the course of which movement the friction pad operates to seat the shoe upon the last, but provision is made for releasing the friction pad from such rearward movement at the will of the operator to avoid straining the shoe. The operating instrumentalities of the illustrated machine are power driven under control of a cyclic mechanism which may not only be started at the will of the operator but which also may be stopped by the operatorat any phase of the cycle.

These and other features of the invention, including details of construction and the arrangement of parts, will now be more particularly described with reference to the accompanying drawings, in which,

In the drawings, L designates a last and S designates a shoe which is to be mounted upon the last. The shoe S, as herein illustrated has a very steeply arched shank and is intended later to be supplied with a high heel. The relasting operation, however, is ordinarily carried out before the attachment of the heel. The shoe S has been partially drawn by hand upon the last L and the lastL mounted upon a last pin P of the machine. The shoe engaging instrumentalities of the machine consistof a friction pad F for engaging the bottom of the forepart of the shoe S, a roll R for engaging the bottom of the rear portion of the shoe and a horn H, together with a cooperating gripper G, which engage the rear end of the shoe upper to draw the rear end of the shoe on the last. These shoe engaging instrumentalities are driven in the illustrated machine by a cyclically controlled mechanism which is started by the depression of a treadle T by the operator. This mechanism operates first to bring the friction pad F into engagement with the bottom of the forepart of the shoe and then to move the friction pad rearwardly with respect to the shoe to urge the forepart of the shoe upon the last. The roll R is urged upwardly into engagement with the shank portion of the shoe bottom and is also moved rearwardly so that it operates progressively along the rear portion of the shoe to urge that portion of the shoe upon the last. The horn'H and gripper G operate in conjunction with the roll R to I continued upward movement of the horn H and gripper G serves to withdraw them from the shoe. The last pin P is then unlatched from its operating position and is enabled to swing to a position such that the operator can readily remove the last and shoe from it. The cycle is now complete and the machine automaticallycomestorest. However, the machine may be brought to rest by the operator at any time before the competion of the cycle to avoid straining the shoe or to enable the operator to make any adjustments of the shoe upon the last which may appear desirable. Such stopping of the machine is accomplished by releasing the pressure on the treadle T.

The above-mentioned instrumentalities, to-

gether with the mechanism for operating them,

' will now be described in detail. The supporting j as.

structure of the machine consists of a hollow frame 20 which houses a greater portion of the driving mechanism and which supports a head 22 having an upward gooseneck extension 24 which supports the last pin P. Rigidly mounted upon the head 22 is a bracket 26 for supporting certain fulcrum pins for the operating mechanism as will hereinafter be pointed out.

Journaled in bearings'in the lower portion of the frame or housing 20 is a drive shaft 28 (Figs. 1' and 5) carrying at one end a sprocket wheel which is driven by a chain 32. The chain 32 may be driven by any convenient source of power, for example, by a motor (not shown) carried upon a bracket mounted upon the opposite side of the frame 20. A worm gear 38 rotatably sleeved upon the shaft 28 is driven by a clutch mechanism which will presently be described. Meshing with the worm 38 is a worm wheel 40 which is mounted upon a cam shaft 42 journaled in a bearing in the housing 20 and also in a bearing formed in a supporting web 43 within the housing 20.

The above-mentioned clutch mechanism comprises a driving clutch member 44 fixed upon the shaft 28 and a driven clutch member 46 freely rotatable upon the shaft 28. The driven clutch member 46 is enclosed in a housing 47. The driven clutch member 46 is slidably mounted along'the shaft 28 formovement into and out of driving engagement with the driving clutch mem ber 44 and it is provided with a hub 48 having a driving connection in the form of a tongue and slot coupling 50 with the worm 38 so that the clutch member 46 may slide along the shaft 28 without interruptingthis driving engagement with the worm 38. A compression spring 51 which is interposed between the clutch members 44 and 46 tends constantly to urgethe driven clutch member 46. out of engagement with the driving clutch member 44. The hub .48 has formed in it a circumferential groove 52 into which extends a pair of pins 54 carried by a forked clutch-control lever 56 which has a bell crank extension 58. The lever 56 is fulcrumed upon a pin 60 carried by abracket 62 which is supported by and depends from the frame 20. A dog 64 is pivotally mounted upon a pin 66 carried in the bellcrank extension 58 of the clutch shifting lever 56. Extending upwardly from the dog 64 is an abutment plate '70 the upper edge of which is engageable with the under surface of a latch plate 72 carried upon a lever '74. Thelever 74 is fulcrumed upon a pin 76 carried by the bracket 62, and the outer end of the lever 74, beyond the latch plate '72, is forked. The lever 74 has a bell crank extension 78 to which is pivotally connected one end of a otally connected to a bell crank extension 82 of a lever 84 which is pivotally mounted upon a fulcrum pin 86 carried by a bracket 88 depending from and supported by the frame 20. Mounted upon the lever 84 is a cam roll 90 which engages a cam 92 secured upon the shaft 42. A spring 94 which is'anchored to the housing 20 urges the lever 74 in a clockwise direction as viewed in Fig. 1 and thereby tends to maintain the roll 90 against the cam 92. The treadle T, which is normally supported by a tension spring 95 anchored to the frame 20, is fulcrumed upon a pin 96 carried by the lower portion of the frame 20. Extending upwardly from the treadle T and pivotally connected thereto is a rod 98 carrying a block 100 which engages an abutment plate 102 mounted upon the dog 64 so that depression of the treadle T will first cause the lower edge of the block 100 to bear down upon the plate 102 and thereby to rotate the dog 64 in a counterclockwise direction as viewed in Fig. 5. Integral with the lever arms 56 and 58 is a third arm 104 to which is pivotally connected the: upper end of a rod 105. The lower end portion of the rod 105 is slidably received within a swivel block 106 which is pivotally mounted upon the treadle T. A nut 107, which is adjustably threaded upon the lower end of the rod 105 and which is held in-adjusted position by a lock nut, is engaged by the lower surface of the swivel block 106 upon depression of the treadle T. However, the nut 10'? is preferably adjusted to provide a slight amount of lost motion so that, before the block 106 will-engage the nut 107, the treadle T must be depressed a slight distance below the normal position in which it is held by the spring 95. A tension spring 108 is interposed between the rod 98 and a lug on the dog 64. The spring 108 tends not only to urge the block'100 to the right, as viewed in Fig. 5, but also to urge the dog 64 in a clockwise direction against a stop on the lever arm 58. The end of the lever 74 is forked and straddles the block 100. Secured to and extending between the fork of the lever 74 is a pin 109 against which the inner surface of the block 100 is held by the spring 108. The surface of the block 100 which bears against the pin 109 has a tapered surface which acts as a cam, upon depression of the treadle T, to disengage the lower edge of the block 100 from the plate 102.

The first effect of depressing the treadle T is block 106 to engage the nut 107 and thereby to exert a downward pull upon the rod 105, swinging the lever arms 104, 58 and 56 in a clockwise direction. The plate 70, already occupying a position to the left of the plate 72, is thereby raised up between the forks of the lever 74. As soon as the upper edge of the plate '70 rises above the level of the under surface of the plate '72, the cam surfaceon the block 100 swings the rod 98 to the left, thereby disengaging the dog 64 from the block 100. Continued downward movement of the treadle T operates, through the lever arm 56, to move the driven clutch member 46 to the left and into engagement with the driving clutch member 44. The gear 38 thereupon drives the gear 40, causing rotation of the cam shaft 42.

The cam 92, as shown in Fig. 5, has formed upon it a raised portion which is engaged by the cam roll 90. As the shaft 42 rotates, the raised portion of the cam 92 is carried away from the roll 90, permitting the lever 84 to swing in a clockto raise the lever 74. As soon as the lever 74 is raised the dog 64, already free from the block 100, snaps into its stop position with the plate 70 beneath the plate 72. The operator may stop rotation of the cam shaft 42 at any time by ceasing his downward pressure upon the treadle T and allowing the spring 51 to separate the, clutch elements; and he can start rotation of the cam shaft 42 again by again depressing the treadle. Continued rotation of the cam shaft 42 will bring the raised portion of the cam 92 again into engagement with the roll 90, forcing the lever 84 toward the right and thereby depressing the lever 74. The plate 72 thereupon engages the plate 70, urging the lever arm 58 downwardly and the lever arm 56 toward the right. The clutch elements are thus disengaged and the cam shaft 42 comes to rest. It will be noted that the action of the cam 92 in separating the clutch elements is positive, and that the treadle, through the arm 104 and the link 105, is forcibly raised against any downward pressure which the operator may exert upon it. If, as in the illustrated machine, the cam 92 has only one raised portion, the cycle of operation of the machine will now have been completed. If, on the other hand, more than one raised portion should be provided, the first stage of the cycle will now have been completed. Be-

' fore beginning a new cycle, or another stage of the cycle in the case of a machine designed for more than one stage, it-is necessary to relax the downward pressure upon the treadle. T to enable the treadle to rise still higher. The lower edge of the block will thus be enabled to snap over the plate 102. The machine is now in readiness for further operation, and the next cycle or the next stage of the cycle may be initiated in the same manner as has already been described, by again depressing the treadle.

The last pin P (Fig. 1) is mounted upon a carrier block which is pivotally mounted upon a pin 112 secured in the lower free extremity of the gooseneok extension 24. The carrier block 110 is free to swing about the pivot 112 to move i is also looked in its operating position by mecha nism which is substantially identical with that disclosed in the above-mentioned application Serial No. 595,810.

The shoe engaging instrumentalities F, R, H and G all derive their respective movements from the cam shaft 42. They will now be described in detail together with their operating mechanisms.

The friction pad F consists of a rubber block mounted in a box 146 (Fig. 4) which is trunnioned upon a pair of coaxial pins 142. The trunnion pins 142 constitute a pivotal connection between the ends of a pair of parallel links 144 respectively, and the end of a link 146. The links 144 move in unison and may later be referred to as a single member. The box is normally maintained in the position shown in Fig. 4 by a pair of tension springs 148 (Figs. 3 and 4) which are anchored to the links 144, respectively. These springs urge the box 140 in a counterclockwise direction against a pair of stop screws which are threaded through lugs formed on the links 144 respectively,

and which engage lugs formed on the box." The box 149 isthus held positively against counterclockwise movement beyond the stop position shown in Fig. 4, but it may yield in a clockwise direction against the tension ofthe springs 143. The opposite ends of the links 144 are pivotally mounted upon a pin 148 (Fig. 1') and the pin 148 is carried in a lever 156 fulcrumed upon a pin 152 secured to the bracket 26 of the machine. The link 146 consists of a central web and side flanges the central web being cut away adjacent to the ends to enable the side flanges at one end to straddle the box 140 and at the other end to straddle a forked lever 156 to which the link 146 is pivotally connected by a pin 153. The lever 156 is journaled upon a pin 158 mounted in the head 22. It may here be noted that the pin 158 serves incidentally to secure the bracket 26 to the head 22, additional securing means being provided to prevent movement of the bracket 26 about the pin 158. Pivotally mounted in the forked end of the lever 156 upon a pair of trunnion pins (Fig. 2) is a block 154. Threaded in the block 154 is one end of a rod 160 the lower end of which slides through a block 162 whichis trunnioned upon pins 164 carried upon the forked end of a lever 166 straddling the rod 160. A collar 163 fixed upon the lower end of the rod 160 retains the latter within the block 162. Bearing against the block 162 is the lower end of a coil compression spring 168 the upper end of which bears against an abutment collar 170 which is slidably mounted on the rod 160. The upper end portion of the rod 160 is longitudinally bored and threaded, and it has threaded within it a screw 172 having a square head extending outside of the rod 160 and accessible to the operator for purposes of adjustment. A cross pin 174 (Fig. 4) has its ends secured to the collar 170 and, extends across the rod 160, the walls of the rod 160 being'slotted longitudinally to permit movement of the collar 170 relatively to the rod 160. r The lower end of the screw 172 bears against the cross pin 174, so

that any upward thrust of the spring 168 is transmitted through the collar. 170, the pin 174, the screw 172, the upper end portion of the rod 160, and the block 154 to the lever 156. Such upward thrust of the spring 168 is obtained through the sliding block 162 which bears against the lower end of the spring 168 and which is actuated by the lever 166. The lever 166 is journaled upon a pin 176 which is mounted in the lower portion of the frame, 20. Integral with the lever 166 is a bell-crank extension 178 which carries a cam roll 180 which engages a earn 182 mounted upon the cam shaft 42. It is evident that rotation of the cam shaft 42 in the direction indicated by the arrow of Fig. 2 will first swing the bell-crank comprising the arms 178 and 166 in a counterclockwise direction tending to compress the spring 168 and to raise the pad F against the shoe. The weight of the pad F, together with its operating connections, is sufficient to hold the roll 180 against the-cam 182 even when-the spring 168 is not under compression. After thepad F engages the under surface of the forepart of the shoe S, further rotation of the cam 182 will compress the spring 162. The compression of the spring 162, and therefore the pressure ofthe pad F against the shoe, is determined by the adjustment of the screw 172.

The roll R (Fig. 4) consists of a metal core covered with rubber and idly rotatable upon apin 184 journaled-in a support 185 which extends between twoparallel links 186. Formed in the ends of the links 186 are guideways 187, in which the support 185 may be clamped in any desired positionof adjustment toward and. from the pad F by screws 189 (Fig. 1) The links. 186 at their carried by a lever 190 (Fig. 4) journaled upon the pin 152. The lever 190 consists of a central web and a pair of side flanges, each of the flanges having an extending ear 192. J ournaled in the ears 192 is a pin 194 into which is threaded a sleeve 196. A hand wheel 198 the hub of whichhas a tongue-and-slot connection with the sleeve 196 is provided for adjusting the sleeve 196 in the pin 194. As shown in Fig. 4, the central portion of the web of the lever 190 has formed in it an opening 199 and the upper portion of the sleeve 196 extends through the opening 199 to render the hand wheel 198 accessible to the operator. A rod 200 extends through the sleeve 196 and the hand wheel 198 and has securely clamped upon it a pair of collars 202 which abut respectively the lower end of the sleeve 196 and the upper end of the hand wheel 198 so as to secure the rod 200 against relative longitudinal movement with respect to the sleeve and hand wheel assembly while enabling the sleeve and hand wheel to be turned for purposes of adjustment. The rod 200 extends downwardly through an opening 203 in the bracket 26. The lower end of the rod 200 is pivotally connected to a lever 204 which extends through an opening 205 in the housing 20 and which is fulcrumed upon a pin 208 mounted in the frame 20. The lever 204 has an extension 210 which carries a cam roll 212. A cam 214 which is mounted upon the cam shaft 42 has formed in one of its lateral faces a track or groove 216 which engages'the roll 212 positively to rock the lever 204 in either direction about the pin 208. It will be noted that rotation of the cam 214 will thus serve to rock the lever 204 and to raise and lower the rod 200 thereby rocking the lever 190 about the pin 152 andmoving the roll R in a direction which is substantially lengthwise of the shoe. Forward and rearward adjustment of the roll R is effected by the hand wheel 198.

' Carried upon each of the arms 186 (Fig. 1) is a pin 218. Each of the pins 218 is pivotally connected to theupper end of a link 220 and the lower ends of the links 220 and pivotally connected by pins 222, respectively, to a pair of levers 224 which are fulcrumed upon a rock shaft 226 carried by the frame 20. As shown in Fig. 1, the links 220 and the levers 224'are positioned outside of the frame 20. Secured upon the rock shaft 226 within the housing 20 is a rocker arm 228 (Fig. 4) to which is pivotally connectedby means of a pin 230 the upper end of a rod 232. The lower end of the rod 232 passes freely through a pin 234 which is carried in the end of a lever 236. A retaining collar 238 secured upon the lower end of the rod 232 prevents the red 232'from slipping out of the pin 234. Surrounding the rod 232 and bearing against the pin 234 is a coil compression spring 240 the upper end of which bears against a nut 242 threaded for up and down adjustment upon the rod 232. A look nut 244 is provided for holding the nut'242 in adjusted position. The lever 236 is fulcrumed upon the pin 176 and is provided with a bell-crank extension 246 in the end of which is mounted a cam roll 248. The cam roll 248 rides upon the periphery of a cam 250 mounted upon thecam shaft 42. It will be noted, as shown in Fig. 4, that the rotation of the 'cam shaft 42 will rock the bell-crank arms 246 and 236 to cause the spring 240 to exert an upward thrust tending to rotate the arm 228 and the arms 224 in a counterclockwise direction as viewed in Figs. 1 and 4 and thereby urging the opposite ends are mounted upon a pin 188 which is a roll R yieldingly into engagement with the shoe. It will be evident from the foregoing description that the cam 212 serves to impart to the roll R a component of movement which is substantially lengthwise of the last L and that the cam 250 serves to impart to the roll R a component of movement which is substantially heightwise with respect to the last L. The roll R, by virtue of its heightwise component, will be brought into engagement with the rear portion of the shoe bottom and will urge the rear portion of the shoe upwardly until the shoe bottom comes into contact with the last bottom. Thereafter any'further tendency of the cam 250 to raise the roll R will be taken up by the yielding of the spring 240. The degree of pressure exerted by the spring 240 is adjusted by the nut 242 above described. The weight of the roll R, together with its operating connections, is sufficient to hold the roll 248 against the cam 250 even when the spring 240 is not under compression.

Mechanism has already been described for imparting to the friction pad F a component of movement which is substantially heightwise with respect to the last. The pad F, however, like the roll R, is also given a substantially lengthwise component of bodily or translatory movement. In the case of the pad F this lengthwise component is effected, not by an independent cam mechanism, but by a connection with the lever 190. This connection (Figs. 6, 7 and 8) consists of a link 252 which is pivotally connected at one end by a pin 254 to the lever 190. Mounted upon the link 252 is a rack 255 (Fig. 6) which engages a pinion 256 mounted upon a pin 258 journaled in the arm 150. The link 252 has formed in it a slot 260 within which the pin 258 is relatively slidable. The slot 260 serves to hold the rack 255 in enagement with the pinion 256. Rigidly secured upon the pin 258 is a ratchet wheel 262 (Fig. 8) which is engaged by a pawl 264 pivotally mounted upon a pin 266 secured in the lever 150. The teeth of the ratchet wheel 262 are so arranged as positively to be locked by the pawl 264 against any tendency to counterclockwise movement as viewed in Fig. 8 so that as the lever 190 is moved in a counterclockwise direction the pinion 256 will be see cured or locked in the rack 254 and the movement of the link 252 will thereby cause counterclockwise movement of the link 150. While the pawl 264, therefore, is in engagement with the ratchet wheel 262 the pad F will be advanced toward the heel end of the shoe in unison with the roll R. Upon release, however, of the pawl 264 the pinion 256 is free to rotate and continued movement of the lever 190 will have no effect upon the pad F. The locking and unlocking of the link 252 to the lever 150 is subject to the control of the operatorand is accomplished by movementof a hand lever 268 which is fulcrumed upon the pin 158. The lever 268 has a bell-crank extension upon which is swiveled a block 2'70. Threaded through the block 270 and secured by a nut 272 is a rod 274 the opposite end of which is pivotally connected to an arm 76 of a collar which is rotatably mounted upon the pin 152. Pivotally secured to a tail portion of the pawl 264 is one end of a link 278 the opposite end of which link is pivotally connected to another link 280 which in turn is pivotally mounted upon the upper portion of the bracket 26. The links 278 and 280 together constitute a toggle which when straight serves to hold the pawl 264 out of engagement with the ratchet 262 and which when broken serves to move the pawl 264 into ratchet engaging position. A spring 282 secured at one of its ends to the tail of the pawl 264 and which is anchored at its other end to the link 150 tends to break the toggle and thereby to urge the pawl 264 into engagement with the ratchet. Each of the toggle links 278 and 280 is provided with a lug 284 (Fig. 6) which lugs engage each other to prevent breaking of the toggle when the togglejafter having been straightened, has been moved slightly past its dead center position. It will be noted that the spring 282 serves not only to hold the pawl 264 in engagement butf'also to hold it out of engagement by maintaining the toggle substantially straight when the pivotal connection between the links 278 and 280 have been moved slightly past its dead center. Rotatably mounted upon the pin 152 is an arm 286 (Fig. 8) which is normally held in a stop position by a spring 288 one end of which is secured to the arm 286 and the other end of which is secured to a lug 290. 1 Another arm 292 is also rotatably mounted upon the pin 152 and is normally maintained in a stop position by means of a spring 294 one end of which is secured to the arm 292 and the other end of which is secured to a lug 296. The lugs 290 and 296 of the illustrated machine are in'- tegral and are rigidly secured upon the fulcrum pin 152, which pin is non-rotatably secured in the bracket 26. The stop position of the arm 286 is determined by the engagement of a pm 287, secured in the arm 286, with the lug 290. The stop position of the arm 292 is similarly determined by the engagement of a pin 293, secured in the arm 292, with the lug 296. The toggle is normally broken, with the lever 150 locked to the link 252 as shown in Figs. 1 and 2. The operator, however, can release the lever 150 from the link 252 if there appears to be any danger of further rearward movement of the friction pad F straining the shoe. The release of the lever 150 is accomplished by turning the handle 268 in a clockwise direction as viewed in Fig. 1. Such movement of the handle 268 serves to rotate the member 2'76 in a clockwise direction. A lug 302 (Fig. 2) which is secured to the member 276 carries a pin 304 which engages the arm 292 and moves the arm 292 in a 264 is thus released from the ratchet wheel 262 and the friction pad F may remain stationary against the shoe bottom while the roll R continues to advance. The operator can also reconnect the lever 150 to the link 152 at any time by rotating the handle 268 in a counterclockwise direction as viewed in Fig. 8. Such movement of the handle 268 serves to rotate the member 276 in a counterclockwise direction. A lug 298 extending from the member 276 carries a pi'n 300 which engages the arm 286 and moves the arm against the tension of the spring 288. movement of the arm 286 causes it to engage the toggle, and, by urging the pivotalconnection between the two links of the toggle to the left, to break the toggle. It will be noted that the arms 286 and 292 are normally maintained, by the springs 288 and 294, respectively, a sufficient distance apart to avoid interference with the toggle as the lever 150 moves back and forth.

Provision is made for automatically resetting the toggle at the completionof the cycle of op- Such eration ofthe machine. With this end in view a bracket 306 is secured by means of bolts 308 to the bracket 26. Pivotally mounted in the upper end of the bracket 306 by means of a pin 310 is a member comprising a pair of oppositely extending arms 312 and 314. The arms 312 and 314 are normally held in a stop position by means of a-spring 316 one end of which is secured to the arm 314 and the other end of which is secured to the bracket 306. Assuming now that the toggle has been broken before the completion of the cycle, the return movement of the lever 190 which takes place in a clockwise direction as viewed in Fig. 8 will serve to move the link' 252 toward the right, causing the lefthand end of the slot 260 to engage the pin 258 and thereby to cause the lever 150 also to move in a clockwise direction. The tail of the pawl 264 is provided with an extension 318 which, as

the lever 150 nears the end of its movement to the right, engages the arm 312 and thus rotates the-arm 314 in a clockwise direction about the axis of the pin 310. The lower end of the arm 314 will thereupon engage the arm 286 and cause the latter to move in a counterclockwise direction and to break the toggle, thereby enabling the spring 282 to move the pawl 264 into engagement with the ratchet 262 to lock the'pinion 256 to the rack 255. Upon the starting of another cycle of the machine it is evident that the lever 150 will now move in unison with the lever 190.

The above-described mechanism for automatically connecting the lever 150 to the link 252 0perates to secure the friction pad F in the same position relatively to the roll R, forwardly and rearwardly of the shoe, for each new cycle. This results from the fact that when the lever 150 is released from the link 254 and after the pad F is no longer engaged by the shoe, the lever 150 will be free to swing about the pin 152; and because of its own weight and the weight of the parts associated with it, it will swing in a counterclockwis'e direction, as viewed in Fig. 8, until the pin'258 comes into engagement with the left-hand end of the slot 260. The same result will follow even ifthe operator, after disconnecting the lever 150 from the link 252, should reconnect these two members while the pad F'is held stationary by engagement with the shoe bottom. In that case, it 'is true, the ratchet will be locked with the pin 258 spaced from the lefthand end of the slot 260 owing to the travel of the lever 190 during the period that the pad F and the lever 150 were stationary. However, as soon as the pad F'becomes free from the shoe bottom the lever 150, under the influence of gravity, will swing in a counterclockwise direction un-' til the pin 258 again engages the left-hand end of the slot' 260. The teeth of the ratchet 262 areso inclined as to-permit them to slip as the pinion 256 rolls to the left along the rack 255. Thus the nn 258 will always occupy the same position in the slot 260 whenever the automatic connection takes place, which occurs at the com pletion of every cycle of'operation.

The horn H and gripper G are substantially The socket 326 ispivotally mounted upon a pin 328 secured in the lower portion of the frame 20. The up-and-down movement of the block 329 is effected by means of a cam 3 30 mounted upon the shaft 42. Engageable with the periphery of the cam330 is a cam roll 332 carried by a lever 334 which is fulcrumed upon the pin 208. A pair of parallellinks 336'connect the free end of the lever 334 and the lower end of the tubular member 322 so that rotation of the cam 330 as shown in Fig. 2 serves to impart an upward component of movement to the horn and gripper member. A spring 338, one end of which is connected to the interior of the frame 20 and the other end of which is connected to the lever 334, tends to hold the roll 332 in engagement with the cam 330 and, as permitted by the cam 330, to impart a downward component to the horn and gripper members. A component of movement in a direction more or less forwardly and rearwardly of the machine, is imparted to the horn and gripper members by a mechanism comprising a cam 340 mounted upon the shaft 42. Engageable with the periphery of the cam 340 is a roll 342 mounted upon a lever 344 which is fulcrumed uponthe pin 208. The lever 344 is provided with a bell-crank extension 346 which operates a mechanism indicated generally by the numeral 348 (Fig. 1) for rocking the tubular member 322 about the pin 328. A spring 350 (Fig. 2) secured at one end to the lever 344 and at its other end to the interior of the frame 20 tends to rotate the lever arm 344 in a counterclockwise direction thereby holding the roll 342 in engagement with the earn 340. For a more complete understanding of the details of the construction, arrangement and operation of the horn H and the gripper G, and the mechanism for operating them, reference maybe had to the abovementionedapplication, Serial No. 595,810.

The operation of the illustrated machine as has previously been pointed out is in a single cycle with provision-for the operators stopping the machine at any time during the cycle and also starting it at will at any time after he has stopped it.

. In using the machine, as in relasting turn shoes, the last :L; usually having the shoe S partially mounted by hand thereon, is placed upon the last pin P while the latter occupies the-'upwardly tilted position shown in Figll, and the last is then swung downwardly to operative position as shown in Figs. 1, 2, and 8, the last pin carrier being locked by mechanism substantially like that disclosed in the above mentioned ap plication, Serial No. 595,810, to hold the -last in this position. As the last is being swung downwardly the horn H will; yield to accommodate the heel end of the last and when the last pin.

is-latched in its operative positionthe horn H will extend within the heel end of the shoe and will bear upwardly against the last, holding the last upon the last pin. All of the parts of the machinewill now be in-their initial positions as shown in Figs. 1 and 2.- The operator then depresses the treadle T effecting engagement of the clutch and starting the cycle. As the cam shaft 42 rotates the cam 182 will rock the lever 1'78 in a counterclockwise direction as viewed in Fig.2 and through the arm 166, the spring 168, the rod 160, the lever. 156 and the link 146 will urge the pad F into yielding engagement with the under surface with the forepart of the shoe. Rotation of the cam 214 will then operate to pull the rod 200 downwardly and thereby to'rotate the levers 190 and 150 in a counterclockwise direction as viewed in Fig. 4. The friction pad F is thus urged rearwardly with respect to the last L, seating the forepart of the shoe upon the last. The roll R has not yet been brought into engagement with the shoe. The positions of the various shoe-engaging instrumentalities just before the pad F has completely seated the forepart of the shoe is shown in Fig. 9. Continued rotation of the cam shaft 42 will cause the cam 250, acting through the lever arms 246 and 236, the spring 240, the rod 232, the lever arms 228 and 224, and the links 220, to move the roll R upwardly toward the shoe bottom. In this movement the roll R will engage the shoe bottom rearwardly of the shank and a trifle forwardly of the position shown in Fig. 8. Such upward movement of the roll R will force the rear portion, of the shoe upwardly upon the last. While the roll R is urging the rear portion ofthe shoe upwardly, the roll R is still being moved rearwardly of the shoe by the mechanism associated with the cam 214. The adjustment of the position of the roll R by the hand wheel 198is preferably such as to bring the roll R, at the limit of its rearward movement, almost to the rear end of the shoe but not beyond the rear end of the shoe. The upward movement of the roll R will cause it to press the insole of the shoe against the last bottom before the roll R completes its rearward movement. Any further 105 tendency toward upward movement of the roll R is taken up by the yielding of the spring 240. The roll R is assisted by the horn H and the gripper G in seating the heel end of the shoe upon the last. While the'roll R is operating to push the rear end of the shoe upwardly, the horn and the gripper are brought'into operation by the cams 330 and 340 through mechanism already referred to. The horn and the gripper arethus caused yieldingly to clamp between them the upper of the rear end portion of the shoe, and, with the horn H rocking about the heel end of the last very much in the manner'of a hand-operated shoe horn, the horn and the gripper are raised, drawing the rear end of the shoe upwardly upon the last. It will be noted that the pad F, in completely seating the forepart of the shoe upon the last, will have already moved the shoe rearwardly as far as necessary. Consequently the horn H is not called upon, in the course of its rocking movement, to exert any substantial rearward pull upon the shoe. Its function is rather to guide the shoe upon the last and,- in conjunction with the gripper G, to

"draw the. rear end of the shoe upwardly, thereby assisting theroll R and at the same time overcoming any tendency of the upward thrust of the roll R to crumple the upper of the rear end of the shoe. The horn H and the gripper G will continue to move upwardly and out of engagement with the now lasted shoe; and they are given an "excess upward movement for the purpose, as more fully explained in the above-mentioned applieation, Serial No. 595,810, of causing the last pin latch to be tripped and thereby enabling the last to swing upwardly as shown in Fig. 11. How- 140 ever, before such tripping of the last pin latch the cam mechanism operated by the shaft 42 retracts the pad F and the roll R from engagement with theshoe bottom so. that the lasted shoe will be free to swing upwardly. Further rotation of the 55.5 shaft .42 operates to retract all the shoe-engaging members to their initial positions, and then to stop the machine by disengaging the clutch members 44 and.46.

- In the course ofv theabove-described operation the friction pad F willusually efiect a complete seating of the forepart of the shoe before the roll R has finished its'rearward movement. In such cases the operator ordinarily will find it advisable to manipulate the handle 268 to release the friction pad F from the rearward drive of the lever 190 to avoid straining the shoe. The roll R, being free to rotate idly and being therefore substantially frictionless in its relation to the shoe, may continue its rearward progress without any tendency to draw the shoe rearwardly. Fig. 8 illustrates the positions of the shoe-engaging members with the forward end of the shoe seated upon the last, the friction pad F released from its rearward driving mechanism, and the roll R together with the horn H and gripper G in the process of seating the rear end of the shoe. Fig. 10 shows the positions which these members will occupy at the completion of the seating of the heel end of the shoe.
